I am here to say why I think the Joker is the greatest Villain of all time. Now, Let's get started.To be the best villain ever you have to do something memorable. Whether it comics, the movies,cartoons, video games or whatever. Something everyone knows. Not just comic fans. This has to be something a random guy on the street would know.For example how everyone knows that Bane broke the bat. Or how everyone knows that Doomsday killed Superman.Magneto,Doctor Doom,Darkseid, Lex Luthor and plenty others have done great stuff but nothing we all know. We all know that the Green Goblin killed Gwen Stacy.Now to the Joker we all know the damage and chaos the joker has caused. We know he killed Jason Todd and shot and paralyzed Barbara Gordon.In The animated series we saw the Joker basically destroy Tim Drake. Taking away young Tim's innocence. In The Dark Knight we saw joker turn Gotham's most upstanding citizen Harvey Dent from a person against crime to a person committing crime. And we see Joker cause utter chaos and destruction.In Arkham City we see him kill Talia. Plus a body count of more than 300 . He has made an impact unlike anyone else.
